Abstract (en)

A method performed by a terminal in a wireless communication system, the method comprising: receiving, from a base station, first downlink control information, DCI, scheduling a first physical downlink shared channel, PDSCH, on a serving cell, the first DCI including first information on a slot offset between the first PDSCH and a first hybrid automatic repeat request acknowledgement, HARQ-ACK, for the first PDSCH; receiving, from the base station, second DCI scheduling a second PDSCH on the serving cell, the second DCI including second information on a slot offset between the second PDSCH and a second HARQ-ACK for the second PDSCH, wherein a slot for receiving the second PDSCH is after a slot for receiving the first PDSCH; identifying a first slot for the first HARQ-ACK based on the first information and a second slot for the second HARQ-ACK based on the second information; receiving, from the base station, the first PDSCH on the serving cell based on the first DCI; and receiving, from the base station, the second PDSCH on the serving cell based on the second DCI, in case that the second slot for the second HARQ-ACK is same as or after the first slot for the first HARQ-ACK, wherein, the second PDSCH is not received from the base station, in case that the second slot for the second HARQ-ACK is before the first slot for the first HARQ-ACK.
